• An automated, polymer-assisted strategy for the preparation of urea and thiourea derivatives of 15-membered azalides as potential antimalarial chemotherapeutics

  DOI：10.1016/j.bmc.2011.01.030

  日期：2011.3

  series of 15-membered azalide urea and thiourea derivatives has been synthesized and evaluated for their in vitro antimalarial activity against chloroquine-sensitive (D6), chloroquine/pyremethamine resistant (W2) and multidrug resistant (TM91C235) strains of Plasmodium falciparum. We have developed an effective automated synthetic strategy for the rapid synthesis of urea/thiourea libraries of a macrolide

  合成了一系列15元氮杂内酰胺脲和硫脲衍生物，并评估了它们对恶性疟原虫的氯喹敏感性（D6），氯喹/乙胺嘧啶抗性（W2）和多药耐药性（TM91C235）菌株的体外抗疟活性。我们已经开发出一种有效的自动化合成策略，用于大环内酯支架的尿素/硫脲库的快速合成。使用溶液相策略合成化合物，总收率为50–80％。大多数合成的化合物具有抑制作用。前三种化合物对所有三种菌株的效力比阿奇霉素高30-65倍，阿奇霉素具有抗疟疾活性。
